Background: 2010 ANNUAL STREET MAINTENANCE PROGRAM By: Steven J. Jankowski, City Engineer At tonight's meeting public hearings will be held on Improvement Projects 10 -02 and 10 -04 through 10 -07. The 2010 program also includes IP 10 -01 and IP 10 -03 which include the first seals of recent subdivision streets. Neither of these two projects will be special assessed as monies were escrowed for this purpose. The City has a considerable investment in the 167 miles of bituminous street for which it is responsible. The City has established the practice of applying timely preventative maintenance to the pavements to preserve this investment. Although budget constraints and pavement conditions may alter the actual schedule, the table below presents an idealized timetable for pavement maintenance. Typical Bituminous Street Maintenance Cycle Year Action 0 Construction 5 Sealcoat 12 Sealcoat 19 Overlay 24 Sealcoat CASE #6 The City has had an annual maintenance program since 1981. Through the 1990 program it was the City's policy to assess the entire cost of the maintenance programs. In 1991 the City changed the policy such that 50 percent of the total project cost was assessed, with the City general fund financing the remaining half. This is the third year of a seven year program to phase out the assessment for sealcoating of streets. This year the assessment for sealcoats will be 29% of the total project cost. The assessments for overlays will remain at 50% of the total project cost. The 2010 program consists of seven individual projects addressing the maintenance needs on 16.59 miles of City streets. Projects 10 -01 through 10 -03 which covers 11.44 miles of City streets, will receive a sealcoating preceded by sealing of cracks having widths which exceed one- quarter inch. The 2010 program includes sealcoating of 1.82 miles of MSA streets which includes Sunwood Drive and Rhinestone Street in Ramsey Town Center. In addition to sealcoating the bituminous sections of these streets, concrete repairs will be undertaken on the portion of Sunwood Drive between Zeolite Street and Rhinestone. Projects 10 -04 through IP 10- 07 involve 5.15 miles of street which will receive a one and one -half inch bituminous overlay of the existing bituminous pavement following the repair of failed areas by the Public Works Department. Streets will have deteriorated sections of concrete curbing replaced prior to the overlay work. In addition streets having concrete curb will be milled for a distance of six feet from the curb such that the new bituminous overlay will match neatly with the existing curb line. The 2010 program is proposed to be financed through a number of funding sources including; MSA funds, developer escrows, special assessments, and City general funds. In addition the City share of the 2010 overlays are being funded through TIF. A summary of the anticipated funding is presented below.
